That carburetor isn't an upgrade, it's a downgrade. If you take off air cleaner and look at air intake it's at least 2mm smaller than stock NT, also no adjustability, other than jet changes. Stock NT carburetors are totally underrated because people don't know how to adjust needle and jet them properly. When clean and properly tuned they can feed any stock style cylinder up to a true 80cc without a problem.
Good to know. I almost bought 5. Thanx.
Yup don’t waste money and time on this carb
You said you were gonna fire it up to let us hear the engine, when I heard the music my heart broke😪
😁😆😅🤣😂
Love the boom boom for the vroom vroom..
I like how you have the fuel line resting on the exhaust. Let us know how it works out for you.
He moved it at the end
Feel smart?
Goofy ass
Those expansion chambers don't get very hot, and most higher quality tubing is rated for a higher temp than cheap plastic tubing, so it should survive, but obviously not ideal of course
Kool rig.. It's good to see someone like you represent us big dudes. I'm a big dude myself and I love my motorized bike. Some people don't know how fun and badass this bike's really are
6’7 270 and I rip my own motorized bike all over campus and my college town. These tiny motors can push a ton of weight
I totally agree. I don't need fast. These little bikes can be quite dependable with upgrades and Street legal lighting. I like a bike to have clean lines. Great Vid.
About how many miles per hour did it go Reynolds
@@jerrysanchez6411 instead of counting pirahnas an llamas to go to sleep you can guess how fast it goes as you doze
Facts
Your fuel filter is backwards. Fun video tho, I subed. :)
Is it really lol. I’ll fix that. Thanks
so far I like both your guy's videos
Hey I know you....
This vid is hilariously awesome. Love the project (I'm new to the hobby and trying learn about motorized bicycles before building my own); thanks for sharing!
That line on the exhaust is gonna melt watchout
Josh, you are fantastic, and very helpful, you give me the courage and skills I definitely need!
what an improvement in the power end! the upgrades really worked
Great Video. Thanks Josh
go ngk and expansion chamber. best and cheapest upgrade for any one
I love this build.. 😀 pure fun
Where did you go josh? You make good vids! Make more because I'm sure I'm not the only one that would like to see you back,
Thanks for an entertaining video. I'm starting my 2nd bike build from a bikeberry motor kit; it's my first one from them. My first bike is more or less a Frankenstein of miss matched parts and adapters that I had to get to get things to fit. Kinda a disaster, but still tons of fun. Curious if you have a recommendation for a good old fashion speedometer that would look good on a beach cruiser?
I Love your battle vest...
I'm a misfits fan to the end... 💗💗💗
I got a homemade misfits tatoo when I was 16yrs old... So ungly but I was so cool ..
Love the bike builds
Thank you for sharing
Lol.
thanks for the vid!
Thanx. Fun vid
Stumbled onto this, congrats on the partnership. PS. Does part of you want to get a bunch of gas bike guys together and play some real life 'Road Rash'?. I keep fantasizing about that while I build mine.
the funiest chanel i have find of motorized bikes, lol
I don’t say this often but, you are a very underrated Channel
a regular ignition system, like an old school point system, just closes the gap on a set of points at a certain time, this puts power to the coil, which amplifies the voltage from 12 volts from your magneto, to about 20,000 or more, firing your spark plug. that's why these can shock the hell out of you, although it won't kill you, because of the coil takes 12 volt at let's say 1 amp, and changes the voltage to 20 or 30,000 volts, at 5 milliamp. yeah that's really low powered voltage. so it just shocks you it doesn't kill you. basically, think taser. only difference is a taser has a circuit that flips a switch on and off really fast, making that buzzing sound. you could think of amperage like this: a lot of amps like 200 to 500 amps to start a car, with those gigantic jumper cables, only 12 volts now, and having a little 9 volt battery(close enough voltage for this example, if you don't like it, put two 9 volts together in series and make it 18 volts, and it'll do the same damn thing), with only milliamps of power. and really neither one will shock you. but you lay a wrench over a car battery, it'll glow bright red and weld itself in half in seconds(and probably blow up so don't do that). you put that same wrench across the 9-volt battery, you're lucky to see any spark at all. enough with that. anyway, with a CDI ignition, you've got your usual magneto generating your 12 volts, this charges a capacitor, a capacitor is like a battery that charges in a millisecond and discharges within a millisecond, all the way to a couple of seconds or more depending on the cap. then, a magnet, usually on the outside of the flywheel or magneto, triggers a hall effect switch, which unloads the cap, charged with power, to that 30,000 volt coil, when it goes by that magnet. then it Sparks that spark plug, pow. then the process starts all over again thousands of times per second or something. maybe I taught you something maybe I didn't, I tried. 🥴💢
Btw would you sell one of those Wc80 expansion chambers?
I connect the blue and white together.... if you look inside the two wires are together...
Spark plug with 4 electrodes. Nice! My CDI stopped working while am miles away from home. Btw, to get more speed.. get smaller rear sprocket. My 36t gets me 30mph.
An 80cc does almost 38mph stock gearing. There must be something wrong with your setup.
Hey can you show how to install that vintage Speedometer
Just ordered a spilt pipe exhaust like the one you have. I need a new carb because the stock is trash I also ordered a new throttle. Should probably upgrade my cdi and get a new spark too. Day 2 since getting an old schwinn with an old Chinese motor and I’m already hooked
How did you get the bike to idle with the clutch out?
You mentioned shortening the cable housing.... mine is super short nit much slack and I assume longer cable means the block inside can close more. Do I understand this ok? How much did you shorten? Just a little bit ?
Hello, how long the throttle cable was to fit the new carburetor please?
My carb like that I'm having jetting issues mind you I never took the motor apart when I got it to make sure everything was good to go cause I've noticed some people had issues right off the start with there's my last one ran great got a few more jets to try then I guess im gonna have to dig deeper if that doesn't clear the problem up won't idle at all stalls immediately slight bog too
When are the motorized bike club vest coming out?
About how fast does it go as I'm a big guy myself ND decided to get into this
I want that exhaust...link or where I can find it? I e looked at many different kinds but the sound and looks of that pipe I like alot.
What about the shiny new head that pops up towards the end?
Like how do you prime the hp carb ? The nt carb had the lil pump on the end bt the hp don’t seem to have one?
I'm having a hard time starting mine. It won't start at all. The motor I have is the one that doesnt have a head you can remove.it is a one piece where ur piston is. An tips on getting it to start besides throwing it out an getting a better one. Oh I crack the CDI a little where u put the screws in. I tightened it to much and it cracked around the ear for the screw .
How do you keep the pipe from vibrating loose at the port ? thanks
how do u connect the throttle cable on this carb verse the old
Good info video! Are you still riding the beach cruiser? That thing looks Sweet Bud! 👍👍🤘💪
Your freaking funny...I love your videos...comedy is involved...Thankyou....
Oh and I have a metal throttle do u have a remedy for hooking it up??
Change the jets in that carburetor,. Down to a 65 and you'll see a difference in the 4 stroking, your performance will greatly improve...
Get you some CDH Power front forks, they're triple tree with suspension, thats what i run on my daily driver/race bike
you can find them on amazon
Your engine needs to be mounter on the bike so that the carburetor float bowl is level to the ground. Your float bowl will fill up to its proper level and you will get a better fuel draw from the carburetor. And just maybe the engine will run faster. if you like the way the engine looks mounted that way then you need a manifold pipe that will set the carburetor float bowl at ground level..
I never thought about the bowl having to be level thanks for that!
Hey man I just ordered the same thing for mine I hope it helps I'm getting ready to watch the video I'm watching ads now!
You can get one of those air filters for a regular NT carburetor and if you watch the dyno video the "high performance CDI" gives the same power as a regular CDI so save your money people
This carburator is a better from normal one?
This guy is awesome
Now that I’ve finished my gas bike I’m wondering if I should get a upgraded CDI or perhaps BR tuning CDI stage one for my 49 cc engine. Is it worth the money which is like 26 bucks?
hey brother! i upgraded my throttle & carbi... on the metal throttles! what is the "allen key head bolt in the middle just next 2 where the throttle cable screws into the throttle! hope ya understood me! 🤣🤦🤦
I want to install a better Airfilter. Do i need a New carburetor? Or can i User the standard
I can't figure out my springer ethier. its like not lined up
Did the carb add more speed
Can you please explain to me why when I turn my gas on there’s no gas coming down the line when I unplug it from the carb gas starts to come out the line please get back to me ASAP I just the same carb as you too bc of it
8:18 ME EITHER!
Not much on watching dudes work, but I really enjoyed watching this. a little less music dubbed over media content
It's a ground that's what shuts down these small engine is grounding the coil
Mine try’s to shut off when I try to idle
An you make a video on how to mix your fuel
Warm these chinadoll engines up 100% before riding anywhere. I start the engine then I have a couple of places I can sit at and warm things up.I increase the throttle adjustment pin so it will run at a fast idle unassisted. As it warms the RPM will increase and the popping in the exhaust tone will smooth out as RPM increases. Slow it down a tad. Listen for the RPM increase. I go thru this 3-4 times. The engine will run in a smooth 2 stroke as it warms up. I will be changing the carb main jet one or two steps leaner. For now, I simply leaned the carb needle, second down from the top. This increases engine heat up to 70% power. Main jet is rich, if the engine isn't warmed up completely at full open throttle the engine will 4 stroke. Back off the throttle a bit till the engine smooths, the engine will step back into 2 stroke, the engine will smooth and get a little quieter. The cylinder and head are aluminum, the rings are cast iron, and the cylinder has a chrome surface. All these different metals have different heat expansion rates so they need to be warmed, thermal saturation, equal heat throughout the whole engine.
I'm dead 😂 no boom boom no vroom vroom
Cool video just the music was a bit too much while attempting to hear the new muffler
lmbo "No Boom Boom! No Vroom Vroom!"
can i use the exhaust on a 100cc?
Your motor its ported sr?
I have a question
Is it possible to install an engine cooling water pump like a large motorcycle to reduce engine heat over long distances
second question . Is it possible to travel with it for long distances, for example, 200 km per day? 120 miles a day
If you are talking long distance desert heat I suggest using a bit more oil in fuel mix and securing large copper fins to the stock cylinder head fins and using a jet size to run a little rich, retard timing a degree or more ,increase airflow over engine with fender shaping, keep tires small smooth and air pressure at maximum, reduce aerodynamic drag whenever possible. It’ll run cool enough.over 120 miles with a couple of stops to fuel up or rest eat or drink. Good luck . Hint: buy the USA case bearings for added confidence on long journeys. There is no crankcase to oil all lubrication is done by adding two stroke oil to the gasoline without it the motor will destroy itself in minutes. There are no galleys for water to travel through as this economical gem is air cooled remember the fins? Have a great (Hot) day Sir. I hope this helped.
give more power?
I like that bbr
Hey man coud u help me my goes slowere with it on it
exhaust note sounds like the carb is jetted too rich
I'm not an expert, but it sounds like it's a little bit rich in mixture. I would try (for science) playing with the main jet needle height setting. If it's currently rich (too much fuel compared to air) I'd adjust the needle to sit lower. That way it holds back the fuel a little, relative to the air coming through. There are tons of videos about carb tuning. It's kind of a thing 😆
Thank my brother from another mother. I’ll try that
Definitely too rich go to about a 65 jet should clear up that sputter
Thanks I’ll try that
I just thought it'd be smart to try adjustments before jumping directly to replacing jets 🤷♂️
@@knifecharlatan8912 that carb only has idle adjustment, there are none to be made except jet changes. It's a bit pricey but the Mikuni VM 18 and a 23mm intake are the way to go will run good right out of the box on these little China motors
definitely a longer ride and if it continues to four stroke lean it out 👍🏻
bike is amazing though i love it ive had 2
What is wrong with stock cd
Any one heard of the nt carb from bike berry ? Any reviews?
Right now my bike doesn’t idle. I can start it and run it but when I come to a stop it shuts off. Help please
That sound you're talking about 4 stroking is just your engine running to rich. Lean out your carb a little by tightening carb set screw... go 1/4 turn or less and check engine top end again. It should make it way faster!!
What jet are you running? I cant find any jets do you have any for sale
eBay.wish, Amazon try those three sites
How do you like smelling like exhaust and gas those 2 stroke and nasty my 49 cc 4 stroke goes 37mph locknload I got a good one I put on a high performance carb and exhaust and it rips. With no smell of gas
Make the vest
Its running rich thats what its doing
Come back... Dont stop posting bro
Your fuel line is going to melt if you leave it where it is (on the pipe).
What did u use for the kick start ?
He just pedaled it, the bike was on a bike stand so the rear wheel moves freely
Why you put better carb why?
That sounds like 4 stroking to me. I’d get a set of NT jets(stock my jets fit the hp carb). And start with 69 and work your way down to like 65, or when the for stroking goes away at full throttle. (Stock jet is a 70)
thank you
@@JoshHarrisRides hey brother nice bike and that's a sweet pipe and pretty good carb and yeah it four stroking those cards come way too rich .... like he said a 65-68 will be perfect for that carb it will be so smooth
Dingleberry like rollin dice or pixxin in the wind an it blasting 75mph in your face
does anyone know if there is a cdi that takes away the throttle to drive faster than 40 kmh? does such a thing already exist?
I’ve never heard of that before. I’d like to know too
A little scull face🤣🤣🤣
I got same carb
It needs more air.
Why is the music far louder than the very engine you are making the video about?
Will this carburetor work with four strokes?
No
Yo I need a 415 chain-link
Need help to figure this motor. Full of gas bottom of motor
Full support from Biñan Laguna Philippines host of bless
What’s your mix ratio? Make sure you run 32/1. The instructions may say 16/1 but that’s very bad for your motors life and performance. I think either your mix ratio is off or main jet, it should sound more like a dirtbike, but that’s just my 2 cents
Thank I’ll try that. I’ve been running 16/1 for the break in. It’s about time to swap. I’ll go to 32/1
@@JoshHarrisRides yeah 16/1 is what the Chinese want so it does blow up before it gets out of warranty because they like to be on the safe side. This can be bad for your rings in the long run because they won’t seat properly, i personally started 50/1 on day one. I would start off at 32/1 and then go to 40/1 after. Hope this helps, love your channel can’t wait for another video!
@@lukeriley2721 I’m doing 16/1 while breaking it in.. So should I do more next time?
I use racing oil for 52/1
I’ve been running 40/1 since I got my yd100 out the box 😅
you should REALLY check out LA Hover's channel.
you shud tun the carb and the ignition tming
Awesome but I noticed u kinda got ripped off on the carburetor,
